Chapter 4.2, Problem 2EYU
A sailor drops a pair of binoculars from the “crow’s nest” at the top of a sailing ship’s mast. When the ship is at rest, the binoculars land at the base of the mast. If the ship is moving forward with constant velocity, and air resistance can be ignored, do the binoculars land in front of the mast (toward the front of the ship), at the base of the mast, or behind the mast (toward the rear of the ship)? Explain.

A projectile with a muzzle velocity of 400 meter per second is fired from a gun on top of a cliff 400 meters above sea level. If the projectile hits the ocean surface 40 seconds after the being fired, determine the angle of elevation of the gun.
Your enemy, 20 km distant, fires a mortar round in your general direction. The round has a vertical component of velocity of 200 meters per second. (Assume that this does not change during the engagement.) You are searching the area using a weapon-locating radar. What must your maximum scan time be to ensure at least four opportunities to detect the target before it passes through your “search fence,” which is the elevation sector extending from 0 to 4 degrees above the horizon?
The answer is 1.75 seconds.
An archer fish spies a meal of a grasshopper sitting on a long stalk of grass at the edge of the pond in which he is swimming. The fish is to successfully spit at and strike the grasshopper, which is 0.200 m away horizontally and 0.335 m above his mouth.
What angle (in degrees) above the horizontal must he spit?

- Because of your physics background, you have been hired as a consultant for a newmovie about Galileo. In one scene, he climbs up to the top of a tower and, in frustration over the people who ridicule his theories, throws a rock at a group of them standing on the ground. The rock leaves his hand at 30 degrees from the horizontal. The script calls forthe rock to land 15 m from the base of the tower near a group of his detractors. It isimportant for the script that the rock takes precisely 3.0 seconds to hit the ground sothat there is time for a good expressive close-up. The set coordinator is concerned thatthe rock will hit the ground with too much speed, causing cement chips from the plazato injure on of the high priced actors. You are told to calculate that speed.arrow_forwardIn tennis, one of the primary ways to win a point is by making the ball bounce twice on your opponent's side of the court.
